What is the sum of the digits of the number 7934 when each digit is raised to the power of its index position (starting from the right)?

To find the sum, we calculate: 7^0 + 3^1 + 9^2 + 4^3 = 1 + 3 + 81 + 64 = 149. Thus, the sum of the digits of 7934 when raised to their corresponding index positions is 149.

Math Question: What is the sum of the thousands, hundreds, tens, and units digits in the number 7934?

To find the sum of the digits in 7934, we first break down the number into its individual digits. The thousands digit is 7, the hundreds digit is 9, the tens digit is 3, and the units digit is 4. Adding these digits together (7 + 9 + 3 + 4), we get the sum of 23. Therefore, the sum of the digits in the number 7934 is 23.

What is the largest multiple of 7 less than 7934 that is divisible by both 3 and 5?

To find the largest multiple of 7 less than 7934, we divide 7934 by 7 and round down to the nearest whole number, which is 1133. Now we need to find the largest multiple of 7 less than or equal to 1133 that is divisible by both 3 and 5. To do this, we prime factorize 1133 as 7 * 7 * 23. Since 3 cannot divide evenly into any factor of 1133 (7 and 23), we need to check only multiples of 7. The largest multiple of 7 less than or equal to 1133 is 1127. To check if it is divisible by 5, we look for a multiple of 5 (ending in 0 or 5) nearby. The nearest one is 1125, which is divisible by 5. So, the largest multiple of 7 less than 7934 that is divisible by both 3 and 5 is 1125.
